Page 1 of 7 Data Sheet Cisco VG248 Analog Phone Gateway Figure 1 Cisco VG248 Analog Phone Gateway Overview The Cisco VG248 Analog Phone Gateway is a mixed-environment solution, enabled by Cisco AVVID (Architecture for Voice, Video and Integrated Data), which allows organizations to support their legacy analog devices while taking advantage of the new opportunities afforded through the use of IP telephony. The Cisco VG248 is a high-density gateway for using analog phones, fax machines, modems, voice mail systems, and speakerphones within an enterprise voice system based on Cisco CallManager. It is advantageous to have these devices tightly integrated with the rest of the IP-based phone system, for increased manageability, scalability, and cost-effectiveness (see Figure 2). The Cisco VG248 offers 48 fully featured analog phone lines to be used as extensions to the Cisco CallManager system in a very compact 19-inch rack-mount chassis. Key Features and Benefits Analog phones—Full-feature analog phone connectivity is needed when the infrastructure (wiring) or application does not support or require IP phones. Full-featured analog phone lines allow organizations to deploy IP telephony without having to purchase IP phones for all the users. Fax and modem—Fax machine and modem connectivity are required in many locations for business needs, and the Cisco VG248 is the ideal device to provide the lines for them. Fax machine and modem connectivity allows organizations to support these legacy devices alongside the New World IP telephones. Voice mail—Many legacy voice mail systems require analog and Simple Messaging Desktop Interface (SMDI) connectivity. Voice mail support allows support for legacy voice mail systems with Cisco CallManager in more configurations and with higher reliability than was previously possible. Investment protection—Customers can continue to use existing phones, fax machines, and voice mail systems while taking advantage of IP telephony. Reduced barrier to entry—Providing a low-cost alternative for low-end analog phones, organizations can take advantage of IP telephony with a lower overall investment in this new technology.

Page 2 of 7 Figure 2 Analog Device Integration with Cisco VG248 Analog Phone Connectivity The Cisco VG248 is ideal for implementations in which it is necessary to use analog phones because it provides a high level of functionality at those locations, including: • Caller ID—The Cisco VG248 supports caller ID (both name and number), so users can tell who is calling before answering the phone. • Message-waiting light—The Cisco VG248 supports two methods of analog light activation: high-DC voltage
